Wireless Power Management

[Copyright]

Okay, I know there's a problem with the devices going to sleep, and I know that people have a fix which works. The only problem is, my device doesn't have power management:

I really don't know what to do, but I'm definitely not going back to Vista, so will someone please help me?

EDIT: I forgot to mention that the driver installed successfully, and there aren't any updates for it.

hello Copyright and welcome to the forums
if you see below where it says power state mapping which says which are supported..
from what i can see this should be supported....
like i said my tut here disables the adapter before the computer goes to sleep so it shouldnt matter whether its power state is enabled...
i cant tell completely if you dont have power management but if you look lower like i have here...

you can see that the S1 S3 states (i think you know what means) are translated into D1 D3 ect and are arranged like you see here in mine i dont have dcap wake from D(X) and my computer can come out sleep fine (used to happend on 7000 x64 but not anymore on 7048)

unless i can see the lower half i can be for certain
if you want you can give vista drivers if you have not tried them..

Here is the bottom section:

I think you misunderstand my problem. My wireless card just stops working randomly, and I believe it's because Windows is putting it to sleep.

aww i see
but randomly?
you cant detect a pattern?
on the facts it says that if you have

# Wireless networking


In certain wireless adapter and platform combinations, the wireless adapter may become disabled and no wireless network will be visible in the following scenarios:

* When the computer resumes from the hibernate or sleep states
* When the computer is processing multiple video streams simultaneously over the wireless link
* Computers that have Microsoft Virtual PC installed

If your computer has Microsoft Virtual PC installed, you may be able to avoid this issue by uninstalling it. In all cases, if this occurs, restart the computer.

i have used MVPC SP1 and without issues...

Those aren't the problems, a few others using Windows 7 have had the issue where their device goes to sleep randomly, for example on my LAN connection under Power Management: "Allow the computer to turn off this device to save power".

 

[darkassain]

maybe changing this settings on the power options may help
especially the USB setting to disabled should help

since you are using a USB device it would also be helpful if you disable the power management on that USB hub...
you will have to do some searching here in the device manager to find which hub is adapter conected

here is a example
once you find go here and change it

Ok, this didn't seem to work, I'm not sure what to do now. There are only two things I can think of, the driver, and the fact the card is a dual-band N card, and my router is G.

 

[darkassain]

ok you have to explain a bit more
is the card disabling as it needs to be enabled or is it disconnecting from the AP (access point?)

It's not disconnecting from the access point, it just stops working period. Like there is a green light that flashes on it, and when it "disconnects" the light disappears.

Hi,
Could anyone help me with my issue. My machine is windows XP.

When my machine was waked up from standby I found my wireless network was not connected. And I also found that wireless adapter was missing from my network connections window.
After I did a reboot of my laptop, wireless adpater was back in network connections.But wireless network was not connected and I found that Power management tab was missing under device manager tab of wireless adapter. I understood that this is in someway related to S3 issue, but not sure how to get my network back.
Kindly help me in resolving this issue.
Thanks in advance.
